LIGHT-SUPPORT.

Application filed December 24, 1918. .Serial No.,268,208.

To all whom it may. concern:

Be it known that I, THEODORE BERMAN, a citizen of the United States, residing at Sioux City, in the county of lVoodbury, State of Iowa, have invented certain new and useful Improvements in Light Supports; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in electric light supports.

One object of the present invention is to provide a novel and improved device by means of which the electric lamp can be moved vertically or horizontally into any position desired by the user. j

Another object is to provide a novel construction of device of this character wherein the electric conductors are prevented from being twisted when the support is turned in the adjusting thereof.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of my improved electric light support.

Fig. 2 is a front view of the same.

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a horizontal sectional view taken on the line 44 of Fig. 2.

Fig. 5 is an enlarged perspective view of the gripping members 27, the member 24: being broken away.

Fig. 6 is a perspective view of one end of the adjustable arm of the device.

Referring particularly to the accompanying drawing, 10 represents a bowl-shaped member which is provided with the apertured flanges 11 for the reception of fastening devices 12, whereby said bowl is capable of being secured to a ceiling or wall over the opening through which the electrical conductors 13 are disposed. In the center of the bottom of this member 10 there is formed a threaded opening 14 into which is screwed the externally threaded neck portion 15 of the conical member 16. This conical member is preferably hollow, as shown in the sectional views of the drawing, and through the said neck portion the conductors 13 are bers 19 are disposed in embracing relation with a spherical member 20. Into this member 20, and between the members 19,v is screwed one end of an arm 21. The memher 20 is formed with an L-shaped opening therethrough, the horizontal portion of which alines with the central bore 22 of the arm 21, for the passage therethrough of the electrical conductors. The outer face of the spherical member 20 is formed with ribs 20 .which interlock avith .similar'ribs 19 on the inner faces of the members 19, thus permitting the member 20 to be securely held at any adjusted position.

Two of the opposite faces of the arm 21 are formed with the transverse corrugations 23. It will be noted that the said arm 21 is rectangular in cross section. A hollow arm 24, which is also rectangular in cross section, except for a portion 25, at one end, which is cylindrical and externally threaded, has its rectangular end formed with the wings 26 which are pivotally connected with the gripping members or arms 27. Secured to these arms 27, and extending therebetween, are the coil springs 28 which normally urge said arms toward each other and facilitate their engagement with the corrugations 23 of the arm 21. The free ends of the arms 27 are formed with the rolled portions 29 which readily engage in the corrugations and hold the arms in proper engaged position.

The before-mentioned threaded portion 25 is engaged in one side of a spherical member 30. Semi-spherical members 31, similar to the members 19, are engaged with this member 31, as shown. Arms 32 are carried by the members 31, and each arm is formed with a section 33 of a ring, the ends being detachably and adjustably connected by the screws 34. In this ring, and between the arms 32, a lamp shade (not shown) is engaged. A pair of resilient arms 35 are secured to the arms 32 and extend downwardly beyond the ring 33, a short distance,

where they are provided with the lamp gripping ring sections 39, and bolts 39". A bolt 38 is disposed'through the arms 32 to clamp the said sections 31 in engagement with the spherical member 80.

Disposed through the lower portions of the arms or legs 18 is a'bolt 36, one end having engaged thereon a Winged nut 37, whereby, upon turning said nut the legs and the semi-spherical members carried thereby Will be moved inwardly tofirmly grip the spherical member 20. Thus'the arm 21 can be swung to the desired'angle and secured in such position by the said bolt and nut.

What is claimed is: I

' 1. An electric light support including a wall member, a depending conical member engaged therewith, a second conical member engaged on the first conical member and rotatable with respect thereto, resilient legs carried by and depending from the second conical member, semi-spherical members carried by the other ends of said legs, a spherical member engaged between said semispherical members, and means on the spheri cal member for supporting an electric lamp. 7 2L'An electric light support including a copies or this patent may be obtained for Wall member, a depending conical member engaged therewith, a second conical member engaged rotatably on the first conical member, resilient legs carried by and de-. pending from the second conical member,

ternally ribbed face, andmeans on .the

spherical member for supporting an electric lamp. 7

8. An electric light support including a 7 wall member, a depending conical member engaged therewith, a second conical member rotatable on the'first conical member, re-

silient legs dependin from the second con ical member, a member adjustable and rotatable between the legs, an arm carried by the adjustable member, a'member slidably adjustable on said arms, and means on the other end of the last-named member for supporting a lamp. I

In testimony whereofI aflix my signature of "tWo witnesses.

in the presence THEODORE BERMAN.
